EXHAUST GAS HEATERS	GESAB-HTI Exhaust Gas Heaters, heated by waste gases from the vessels's main engine, is commonly used in satisfying the heat demand of the vessel's bunker heating, accommodation, calorifier water and pre-heaters during the voyage. It may also be sufficient to heat the cargo, subject to heat requirement.

EXHAUST BOILERS

Parat exhaust boilers for hot water and steam.

Utilizing the waste heat from engines and generators is a good way to save fuel and space and at the same time reduce harmful emissions to the atmosphere . Parat specializes in custom designed boilers and economizers for any vessel and engine type with the focus on providing the user with the most compact and efficient solution available.

Since the worlds first composite boiler left our factory in 1972, we have continued innovating and are able to supply any standard or custom made heat recovery solution for all kinds of engines or generators. The following pages give a brief overview of our products under the category exhaust gas boilers.

EXHAUST GAS SMOKE TUBE BOILER The smoke tubes pass through the boiler and the exhaust gas flows inside the tubes. This construction makes the boiler suitable for connection to more than one engine with separate exhaust gas sections in one boiler.

The boiler can either work with forced circulation with evaporation in a separate steam drum or as a natural circulating boiler with a built-in steam drum at the top.

The boiler can be controlled by a surpuls valve and a condenser, or by a three-way exhaust gas damper. The boiler is pre-assembled and delivered as a complete unit.

EXHAUST GAS WATER TUBE BOILER The water tube boiler consists of finned tube or bare tube bundles mounted together in sections.

The water circulates through the tubes and the extended heating surface on the exhaust gas side makes this boiler compact. The water flow is generated by circulation pumps and evaporation takes place in the boiler. The water/steam mixture is then separated in a steam drum or in an auxiliary boiler.

The boiler can be controlled by a surpuls valve and a condenser, or by a three-way exhaust gas damper. The boilers are pre-assembled and delivered as a complete unit. Needs proper water treatment and cleaning.

SMOKE TUBE / EXHAUST GAS BOILER The boiler is of vertical design with smoke tubes through the boiler and steam evaporation at the upper section. The boiler is constructed from drawings approved by all classification societies and delivered with equipment in accordance with class requirements. The combination of both an oil fired section and exhaust gas section in the same boiler leads to a simpler and more economical steam system on board. A two in one system is less expensive to install than two separate boilers. A combined system is easy to service and maintain, thus providing cost savings during the lifetime of the ship. Capacity of the exhaust gas section will depend on the exhaust gas quantity and temperature.

The principle of the boiler is based on a common water and steam space and separate sections for oil firing and exhaust gas. If several engines are utilized, the boiler can be delivered with several separate exhaust gas sections. The boiler comprises smoke tubes both for the oil fired and the exhaust gas section. From the top of the boiler there is good access to the tubes which make service and maintenance easy.

A main feature of the boiler is its automatic mode. When this mode is activated, the exhaust gas section becomes the main heating source. If the capacity is too small and the steam pressure drops, the oil burner automatically ensures correct pressure. The control system is designed to enable an unmanned engine room. The system is fully automatic and operates with electronic controllers and electric/pneumatic actuators. The panel is mounted on the boiler side. Operation of the boiler control panel is done from the local touch screen. Boiler PLC can be connected to the main control system by standard ethernet/profibus/modbus communication.
